NCT07002658

Brief Summary

The goal of this clinical trial is to compare two different techniques: endoscopic saphenous vein harvesting versus conventional open harvesting in patients undergoing coronary artery bypass grafting, either alone or in combination with another cardiac surgical procedure (valve surgery or arrhythmia surgery). The main questions the trial aims to answer are: Does the endoscopic technique reduce surgical wound morbidity in terms of shorter hospital stays? Does endoscopic saphenous harvesting reduce the use of antibiotics for saphenectomy wound infections? Does the endoscopic technique reduce need for wound dressings due to necrosis and/or wound infection, and reduce need for analgesic treatment for wound pain? This prospective, randomized study will be conducted in the Cardiovascular Surgery Service at Hospital Clínico San Carlos. Participants will be randomly assigned to a different saphenectomy technique. All patients will be assessed for saphenectomy wound complications upon discharge, and by phone call at 7 days, 1 month, and 3 months following the intervention.

Outcome Measures

Primary Outcomes (1)

  • Wound morbidity

    Days of hospital stay, use of antibiotics for saphenectomy wound infections, need for wound dressings due to necrosis and/or wound infection, and need for analgesic treatment for wound pain. 1. Length of Hospital Stay. Unit of Measure: Days 2. Use of Antibiotics for Saphenectomy Wound Infections Measure: Number of participants requiring oral or parenteral antibiotics due to wound infection. Unit of Measure: Participants 3. Need for Wound Dressings Due to Necrosis and/or Infection Measure: Number of participants requiring wound dressings due to necrosis and/or wound infection. Unit of Measure: Participants 4. Use of Analgesics for Wound Pain Measure: Number of participants requiring analgesic treatment for saphenectomy wound pain

    From enrollment to the three-month follow-up visit

Secondary Outcomes (1)

  • Freedom from combined cardiac events

    1 year

Study Arms (2)

Endoscopic saphenectomy

EXPERIMENTAL

Endoscopic vein harvesting in CABG surgery requiring a vein graft with or without extracorporeal circulation

Procedure: Harvesting of the saphenous vein graft

Conventional and open technique for saphenous vein harvesting

ACTIVE COMPARATOR

Using the conventional open technique for harvesting the saphenous vein in any type of surgery with or without extracorporeal circulation

Procedure: Harvesting of the saphenous vein graft

Interventions

Most existing studies on endoscopic saphenectomy have been conducted in CABG with cardiopulmonary bypass (CBP), whereas most CABG surgeries at the study center are performed without CBP. The following outcomes will be identified: * Days of admission or need for hospitalization * Use of antibiotic therapy for saphenectomy wound infections * Need for wound dressings due to necrosis and/or wound infection * Need for analgesic treatment for wound pain

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients undergoing coronary artery bypass grafting (CABG), alone or in combination with other surgery (valve or arrhythmia surgery), with or without cardiopulmonary bypass (CPB), in which preoperative evaluation includes the plan to use a short saphenous vein segment (alone or in addition to arterial conduits).
  • Availability of a surgeon or cardiac surgery resident trained in endoscopic harvesting in the operating room.
  • Patients undergoing myocardial revascularization surgeries with or without extracorporeal circulation.
  • Patients undergoing concomitant cardiac valve replacement surgery, atrial fibrillation surgery, and others, in addition to CABG

You may not qualify if:

  • Emergent surgery or procedures performed during cardiorespiratory arrest
  • Myocardial revascularization with arterial grafts only
  • Presence of varicose veins
  • History of infrainguinal vascular surgery
  • Presence of ulcers and/or active infection in the lower limbs
  • Previous stroke with neurological sequelae in the legs
  • History of deep vein thrombosis in the legs
  • Pregnancy
  • Age under 18 years
  • Lack of signed informed consent
